hey guys / Girls

 

My stock temp gauge was being erratic..i.e up and down although water level was perfect and water pump etc was changed about 6 months ago..now i know the stock gauge is rubbish plus after a short pause is started working perfectly again. However , during the pause I thought i´d give both temp sensors a little wiggle to check the connections, as I did the secondary ( electric)fan came on and has been on permanently since , anyone got any ideas there?

 

cheers

i think the fan comes on if the sensor is disconnected.

 

Check your ecu for errors

 

and get an aftermarket gauge!

Make an ecu diagnostic...probably the ecu water temperature sensor is malfunction or disconnected.

ah, right..it comes on when the sensor is disconnected ...cheers for that edk83...aftermarket temp gauge is ordered and on it´s way, it should arrive anyday.

 

As for checking ECU codes, I´ve read about you guys all doing that m but looks complicated to me and i´ll probably end up short circuiting the thing and doing more damage than good. great confidence in myself there ey :)

hey its easy i just did it for the first time today ,followed the instructions i found on a search trust me if i can do it then anyone can

Can u tell me where to find instrutions for ecu diagnostics? i havent done one yet

 

 

and yes if your water temp sensor is broke or disconnected then the secondary fan will stay on for safety.

tap in fault code in the seach go onto the thread ecu code reading fault then second post down theres a link ,sorry dont know how to cut and paste links

Its easy, just a case of shorting two pins with a small amount of wire when the igition is on. Then watching the dash light flashing in seqence to work out the error codes.

cool im not even sure if my engine light bulb works, as i think the previous owner may have had something to hide, hmmmm soon find out.

or this way too

yeah that way looks a bit too long for me i think il do the easy way ;)
